SCREEN.

Application led'January 8, 1925. Serial N o. 1,234. Y l

To all whom t may concer/n.:

Be it known that I, WILLIAMN. CRorrEn, a citizen of the United States ofAmerica, residing at Lexington, in the county of Fayette andv Stat-e ofKentucky, have invented certain new and useful Improvements in Screens,of which the following .is a specification.

My invention relates to improvements i screens and screen construction.

An important object of my invention is to provide a screen with newandimproved means for allowing ready removal or replacement of the netting.

Another object of my invention is the provision of a device of the abovementioned character with Va key member for locking the netting keepersin position. Another object of my invention is to provide a device ofthis character with improved means for pivotal mounting.4 Other objectsand advantages of my invention will be apparent duringthe course of thefollowing description. Y

In the accompanyin drawings which forma part of this speci cation andwherein like characters of reference denote like or corresponding partsthroughout the same, Y

Figures 13 and 14 are detail views illustrating one mode of assemblingthe crossbar, and

Figure 15, is a similar view of another mode of assemblingthe cross-bar.

In the drawings wherein for the purpose of illustration isrshown apreferredA embodiv ment of my invention the numeral 16 designates awindow frame of the usual construc-` tion which is adapted to receivethe screen. This screen. comprises side, top, and bottom channel strips17 which have their sides 18 bent inwardly at an acute .angle therebylforming a substantially*inverted V-shapedvchannel with an opening atthe top, or apexoi' the V. These Achannel strips are adapted to receivesubstantially V,shaped keepers 19l which fit snugly therein. The outerside 18 oil one ot' the side channel strips iscut away at both of itsends, as at 20, as is the outerside of the bottom channel strip.

In assembling, the netting is placed over yond the cutaway portion ofthechannell at one end, in order that the side keeper may be lslid inplace. The key section 22 is sprung into place over the bottom keeper,and its end is bevelled to interlit with the end of the side keeper.When in this position, thekeepe'rs are positively locked in place, andmay not be removed without first removing thefkeyy section. v

The keeper strips and key section are provided with openings 23 for theaccommodation of a nail 24 or ot-her.implement to assist in removingthem from the channels. The screen frame is strengthened by means ofstay rods 25 which are provided at their ends with head portions 26.`The inner sides of the channels are provided with openings `or' the sizeof thestay rod, the sides ofwhich are slitas at 27 and struck upl at 28in order to receive the head 26 of the stay rod. VWhen the rodsare inplace, the struck up portions 28 are pressed back into their originalposition, as shown in Figure 14:, and the rodsV are locked in position.

In the form shown in Figure 15,` the large openings 30 open into thesmaller openings 31, and when the rod isin position and the nettingclamped in place the rod will be securely held.

A plate 32 is rigidly secured to the upper Aother stud, and these rodsare connected by an internally screwthreaded coupling member 39. In theform shown in Figurel 4, the rod 38 is provided with an enlarged head 40which engages a recess 4l in the coupling. rIhe coupling member willrotate 'freely on the rod 38 and will engage the threads on the rod 37to move the same. It will be seen that rotation of the coupling willproject the pivot bolts into the openings 42 and will lock them thereuntil they are retracted by rotation of the coupling member.

In the form shown in Figures 5 and 6, the rod 38 is not positivelyconnected to this coupling but has a reduced portion 43 which extendsinto the coupling, which abuts against the shoulder 44 formed by thereduced portion. In this form ofl my invention the coupling only servesto lock the bolts in their extended position. When it is desired towithdraw the pivot bolts, thecoupling is screwed onto the rod 37 untilthe rods fall apart, as in Figure 6, and the bolts may then be manuallywithdrawn.

A prop or support isformed by the rod 45 which encircles the upper stayrod adjacent one side of the screen and extends nearly to the bottom ofthe screen where it is bent upon itself to form an eye 46 and then eX-tends back to apoint adjacent the stay rod where it is twisted aboutitself and extended transversely of the screen parallel to the staylVhen it is desired to'raise the screen, the

eye 46 is hooked over a nail or stud 46 to support the screen in itsraised position. It will be seen that the prop will support both sidesof the screen and cause it to hang straight although it is arrangednearly entirely on one side of the screen.

A chain 47 or the like is secured to the plate 32 in order that thescreen may be hung up in a convenient location when not in use. A hookor catch 48 is secured to the window sill and engages an opening in thelower channel strip to retain the screen in its closed position. l

While I have shown and described the preferred embodiment ot' myinvention it is to be understood that various changes Yin the size,shape, and arrangement of parts may be resorted to without departingfrom the spirit of my invention or the scope of the subjoined claims.

Having described my invention what I claim as new and desire to protectby Letters Patent is:

l. A `screen comprising substantially V- shaped channels, andsubstantially V-shaped keepers adapted to be slid longitudinally intosaid channels.

2. A screenv comprising substantially V- shaped channels, andsubstantially V-shaped keepers adapted to be received therein, saidchannels having certain of their ends provided with cutaway portions toallow insertion of the keepers.

3. A screen comprising substantially V- shaped channels,` andsubstantially V-shaped keepers adapted to be received therein, saidchannels having certain of their ends provided with cutaway portions toallow insertion of the keepers, one of said keepers terminating short otthe channel. in which it is received, and a key keeper section adaptedto be arranged over said shortkeeper to complement .the same, and lockthe keepers in the channels.

4. A screen comprising channels, the sides of. said channels beinginclined towards each other, netting adapted to be arranged over theinner sides of the channels, keepers adapted to be arranged within thechannels, certain of the ends of the outer sides ot the channels beingcut away to allow insertion of the keepers, oney of said keepersterminating: short of the channel in which it is received, a key keepersection adapted to complement .said short keeper and lock all of thekeepers in position, stay rods connecting the inner sides of the sidechannels. and a prop arranged adjacent one side of the screen andengaging both ends of the stay rodto properly support the screen.

5. A'screen comprising substantially V- shaped channels, substantiallyV-shaped keepers adapted to be received therein, said channels havingcertain of their ends provided with cutaway portions to allow insertionof the keepers, one ot said keepers terminating short of the channel inwhich it is received, a key keeper section adapted to be arranged oversaid short keeper' to comple- 115 ment the same and to lock the keepersin the channels, a sleeve secured to the upper channel, pivot boltsslidably arranged in the sleeve, and means to project said bolts andloc-k the same.

In testimony whereof I affix my signature.

WILLIAM N. CIOPPER.
